Model S flow meters

Model S single tube flow meters are similar to P meters in design, employing the same interchangeable flow tubes, valves, and accessories. Likewise they may be panel or bench mounted. The primary advantage of the S meter is convenience in applications, where frequent changing of tubes in meter cases is desired. An example is when several flow tubes are used in conjunction with a single meter case, or when because of the nature of the fluid, periodic cleaning necessitates disassembly.

Exclusive design facilitates simple installation and replacement of tubes in mounting cases. As a result of the “non-rotating” adapter feature, glass flow tubes are prevented from turning during the tightening phase of the assembly procedure.

Flow tubes for these meters are available with two types of scales, suitable for different types of applications.

Meters are available with built-in needle valves (CV™), high precision metering valves (MFV™) with “non-rising stems”, or with no valves. The higher cost of MFV™ valves is justified whenever high sensitivity control and resolution are desirable particularly in conjunction with metering tubes of very low flowrates.
